Ohaguro

Ohaguro(お歯黒) is a custom of dyeing one's teeth black. It was most popular in Japan until the Meiji era. Tooth painting is also known and practiced in the southeastern parts of China, Pacific Islands and Southeast Asia. Dyeing is mainly done by married women, though occasionally men do it as well. It was also beneficial, as it prevented tooth decay, in a similar fashion to modern dental sealants.

In Japan, Ohaguro existed in one form or another for hundreds of years and was seen amongst the population as beautiful until the end of the Meiji period. Objects that were pitch black, such as glaze-like lacquer, were seen as beautiful.

The word "ohaguro" was a Japanese aristocratic term. There is an alternate reading for ohaguro, 鉄漿 (literally 'iron drink' "lead"). At the old Imperial palace in Kyoto, it was called fushimizu(五倍子水). Among the civilians, such words as kanetsuke(鉄漿付け), tsukegane(つけがね) and hagurome(歯黒め) were used.

References to ohaguro exist in The Tale of Genji[1] and Tsutsumi Chūnagon Monogatari. At the end of the Heian period, at the time when aristocratic men and woman reached puberty and celebrated their genpuku or mogi, the Taira clan and other samurai, and pages working at large temples, dyed their teeth. In particular, the imperial family and other high-ranking aristocrats who had finished their hakamaza (ceremony where a child is fitted with a hakama) blackened their teeth and painted their eyebrows (hikimayu(引眉)). This was done in the imperial household until the end of the Edo era.

In the Muromachi period, ohaguro was generally seen among adults, though when the Sengoku period arrived, so as to prepare for political marriages of convenience, when the daughters of military commanders were around 8 to 10 years old, they would blacken their teeth as a marking of their coming of age. Relatives and guardians of the bride who blackened their teeth were called kaneoya (鉄漿親). It is said that military commanders who were struck in the head on the battlefield and who did not want to be ugly[citation needed] would wear average women's makeup and would blacken their teeth. These faces imitated the Noh masks of women and young boys.

After the Edo period, only men of the Imperial House of Japan and the aristocracy blackened their teeth. Due to the odor and labor required for the process, as well as a feeling among young women that they were aging, ohaguro was done only by married women, unmarried women who were older than 18, sex workers and geisha. For rural people, ohaguro was done only at times of special celebrations, such as Japanese festivals, wedding ceremonies, and funerals. There were also depictions of ohaguro in fairy tales, such as "Gon, the Little Fox".

On February 5, 1870, the government banned ohaguro and the process gradually became obsolete. After the Meiji period, it temporarily spread, but it almost entirely died out in the Taishō period (ending in 1927).

In contemporary times, the only places where ohaguro can be seen is in plays, hanamachi (geisha districts), some festivals, and movies.

Many Westerners, including Engelbert Kaempfer, Philipp Franz von Siebold, and Rutherford Alcock, who visited Edo-era Japan, described ohaguro as an abhorrent custom which disfigured women.[2] Alcock conjectured that the purpose of it is chastity by making the women intentionally unattractive to prevent potential extra-marital relationship. Japanese social scientist Kyouji Watanabe disagrees with this theory. Based on the fact that Japanese girls were allowed a large degree of both social and sexual liberty until the time of Ohaguro when they resume the responsibility of wife and mother, Watanabe thinks that it is a social ritual by which both society and a girl herself confirm the determination of matured women.[3]

The main ingredient was a dark-brown solution of ferric acetate called kanemizu (かねみず), made by dissolving iron filings in vinegar. When the solution was combined with vegetable tannins from such sources as gallnut powder or tea powder, it would turn black and become non-water-soluble, in the same manner that iron gall ink is produced. Coating the teeth with this liquid helped to prevent tooth decay and enamel decay. The dye had to be applied once a day or once every few days.

As a convenient prescription, a fine powder of gallnut powder, sulfuric acid, and oyster shell could also be applied to the teeth, though this never really caught on.

In theatrical plays, ink mixed with turpentine was used, though these days, ink mixed with tooth wax is used.

In the Meiji, a rumor spread about an area where a virgin's blood was painted on an electric line. As a result of not wanting to have their blood taken as well, many of the young women in this area changed their appearances to match those of married women by blackening their teeth, painting their eyebrows and wearing simple kimono.

In Yamada Norio's 2010 book "A Trip of Tōhoku Ghost Stories" (山田野理夫東北怪談全集), a story about Fukushima Prefecture is described (お歯黒べったり, "Ohaguro Bettari").

The practice of blackening teeth[specify] continues among many minority groups in China, Pacific Islands and Southeast Asia. It is mainly prevalent in older women, though the practice is still carried on by some younger women. Sometimes artificial teeth are used to achieve blackened teeth.

The agent of choice for teeth blackening became known as missī, a powdery mixture of (1) iron and copper sulphate, (2) a plant source of tannins, such as myrobalans, and (3) flavouring agents. The use of missī, thought to be sanctified by Fāṭimah, the Prophet's daughter, became deeply engrained in Islamic culture across much of the subcontinent. Teeth blackening as a life cycle event related to sexual maturity and in its literary portrayals acquired distinct sexual overtones. It was integrated into to the culture of courtesans and prostitutes where missī became synonymous with the ritual of selling a woman’s virginity. Although not a primary motivation, medicinal considerations also played a role in the use of missī. Early references to blackening the gums and edges of the teeth suggest a connection to an older tradition of filing the interstices between teeth which had become prohibited by Islamic law. Geographically and culturally distinct traditions of teeth blackening also prevailed among diverse indigenous groups living along the slopes of the Eastern Himalayas, from Nepal through Meghalaya and Assam to Nagaland.[5]

Further west, teeth blackening has been documented as far as Madagascar.[6]
